Abstract (en)
[origin: WO9627075A1] A power turbine system operating in an organic Rankine cycle with a thermodynamic medium flowing therethrough, including a power turbine (10) having an inlet connected to a conduit (50) and an exhaust (14), a lower temperature engine system having a heat engine, a circulating thermodynamic turbine medium flowing through the heat engine and producing rejected waste heat during engine system operation, a regenerative heat transfer device (6) for heating the turbine medium from the turbine exhaust to produce liquid phase turbine medium at an elevated temperature, a pump (28) for pumping the liquid phase turbine medium at the elevated temperature as a first boiler feed return stream, a boiler feed return stream conduit (50) for conducting the boiler feed return stream to the turbine (10) through branch conduits (51, 52), injectors (53, 54), a pump (55), and a boiler vessel (56) for heating the turbine medium to be fed to the turbine inlet. The injectors are positioned along the turbine cycle between successive stages and are controlled by controlling the mass flow of the injected liquid phase turbine medium into the turbine for effecting a selected vapor quality of the resulting mixture.
